About this entry
80% of key specs known. Missing: weight, hardening, bracelet offered.
CuSn8 bronze version of the Hammerhead 43 Field, listed by Zelos on 27 May 2026 in three colourways at $499; the steel Hammerhead 43 Field (April 2026, including the DLC Storm) is a separate model. Same specs as the steel one: 43mm, 48mm lug to lug, 13mm thick with crystal, 22mm lugs, 300m, Seiko NH38 without a date, domed sapphire with inner AR coating, Super-LumiNova C3 and BGW9 with Lumicast 3/6/9 indices (Vesper has blue Super-LumiNova). Fixed bronze bezel, screw-down crown and solid caseback per SeriousWatches. Sold on an FKM rubber strap with a bronze buckle; Zelos also sells a full bronze bracelet for the Field separately ($219), layered with a steel underside so the bronze doesn't touch the skin, so the bracelet fields are left blank rather than "not offered". All three colourways were sold out at Zelos and SeriousWatches on 2026-10-21; the model is still in Zelos's Hammerhead collection, not in Discontinued Models. Hardening and weight not stated.
